The Dangers of Mixing Alcohol and Antibiotics

Early in vitro studies suggested that metronidazole or its metabolites inhibited liver alcohol dehydrogenase (67,–69). A more recent rat study found that metronidazole and alcohol increased intracolonic acetaldehyde levels, without altering blood levels (70). Alcohol and acetaldehyde levels were measured every 20 min over a 4-h period. Here, we’ll discuss the safety of mixing alcohol and antibiotics.

Not only can they interfere with the way the antibiotics work, but they can also cause a number of harmful side effects. An occasional drink with fluoroquinolone can be safe, but regularly drinking alcohol may cause central nervous system side effects. Mixing alcohol with fluoroquinolone antibiotics such as ciprofloxacin may increase these mental health side effects. People deficient in folic acid may be at risk of further reducing their folic acid levels while taking trimethoprim-sulfamethoxazole. People who regularly drink alcohol may have lower levels of folic acid and should use trimethoprim-sulfamethoxazole with caution. As well as its antibacterial effect, linezolid reduces the action of enzymes called monoamine oxidase-A and monoamine oxidase-B.

Nitroimidazole antimicrobials are a class of antibiotics that stop bacterial growth. This is where a probiotic can be very beneficial while taking an antibiotic. Probiotics are formulated to restore your beneficial bacteria or gut health. A probiotic can potentially decrease the likelihood or decrease the risk of some side effects.

Any abnormal changes to your health or concerns when using antibiotics warrant a call to your healthcare provider. While not all antibiotics will negatively interact with alcohol, it’s vital to practice caution and have clear information regarding alcohol safety with the prescribed medication. Some (but not all) antibiotics interact with alcohol, and different types come with various risks. Following a healthcare provider’s advice is important to determine what is safe for you.

Some of the infections treated by antibiotics include sinus infections, skin, bladder and kidney infections, whooping cough, and strep throat. Isoniazid is used for the treatment of tuberculosis and nontuberculosis mycobacterial infections (98). First-line treatment of pulmonary tuberculosis (TB) involves an initial phase of four agents (isoniazid, pyrazinamide, ethambutol, and rifampin) (98). Treatment is prolonged, with agents known to be hepatotoxic (98). Multidrug-resistant tuberculosis has necessitated the use of second-line agents, which can result in adverse neurological reactions, making concomitant use with alcohol undesirable (99). Concurrent use of alcohol precipitated disulfiram reactions in two patients treated with ketoconazole.

Metronidazole, tinidazole, cefotetan, cefoperazone, and ketoconazole

For example, doxycycline (Vibramycin, Monodox) and amoxicillin (Amoxil) are known to frequently cause digestive problems, says Nouhavandi. Since having alcohol in your system can also cause these symptoms on its own, using both antibiotics and alcohol together increases your risk of these side effects. Alcohol can reduce the eco sober house ma effectiveness of antibiotics, and it can also increase the risk of side effects. However, other antibiotics, such as Bactrim, can interact with alcohol and increase the risk of severe side effects. It is essential to understand the risks of combining antibiotics and alcohol before you decide to drink while on antibiotics.

Other antibiotics can have their own interactions with alcohol, but they are generally less serious.

Incidental and responsible alcohol consumption provides little risk for nonreactive antibiotics.

Can antibiotics cause diarrhea and other side effects?

If you mix alcohol and these antibiotics, it can lead to symptoms like an uncomfortable flushing of the skin, low blood pressure and vomiting. The package labeling recommends against the use of metronidazole and alcohol within 48 h due to the risk of a disulfiram-like reaction (46). Although it is commonly believed that metronidazole mediates disulfiram reactions, data are contradictory. In 1964, a study stated that metronidazole may be effective for alcoholism based on 53 patients who had reduced desires to drink and lower tolerances and reported disulfiram-like reactions (47).

Alcohol is metabolized differently from other drugs, affecting their absorption and toxicity. Here are some examples of drug-alcohol interactions and what you should do if you suspect an interaction. While antibiotics can be beneficial in treating an infection, they can also cause side effects, such as an alcohol hangover.

The reaction resolved with continued ciprofloxacin use and abstention from alcohol. The effect of the PK of the amoxicillin-alcohol interaction was studied in eight healthy volunteers receiving, on three separate occasions, amoxicillin (500 mg) with water or alcohol. The absorption of amoxicillin, when combined with alcohol, was delayed compared to its absorption with administration with water (11).

The Effect of Alcohol on Specific Antibiotics

Mixing alcohol and antibiotics can have various adverse effects. Both drugs can affect the body’s metabolism, making them ineffective in fighting infections.

Can I take antibiotics with alcohol?

Other antibiotics, such as Disulfiram, can increase the risk of alcohol poisoning and cause severe stomach and gastrointestinal problems. Using these drugs together can also result in a severe hangover. The articles were chosen after a search of published English language medical literature. A secondary search was performed via review of references found from the initial search. All randomized controlled trials and results from smaller, nonrandomized, open-label studies were included, provided that the studies had adequate methodology as judged by the authors. For drugs with limited information, case reports/series were included.

  • If you’ve been prescribed an antibiotic for an infection, you may wonder if it’s safe to have a drink or two.
  • Alcohol then not only slows the healing process and recovery time, but additionally puts an individual at increased risk of developing another infection.
  • A total of 87 studies are included in this review, after many were excluded due to duplications or not being relevant to the review (Fig. 1).
  • However, certain antibiotics do require you to refrain from drinking while taking them so you should always discuss this with your prescribing physician.

Also, see the information on the prescription and act on it as it is better for your health. Several antibiotics can interact with alcohol, including cefoperazone, an antifungal that treats salmonella infections. Drinking alcohol can worsen such side effects, and some antibiotics don’t explicitly warn against drinking while on them. The liver has the highest potential for adverse reactions to alcohol. At the end of the day, as with all medications, it’s important to talk openly with your own healthcare professional about the potential effects of mixing alcohol with antibiotics on you.

Alcohol doesn’t make most antibiotics less effective, but consuming alcohol — especially if you drink too much — might increase your chance of experiencing certain side effects. Combining alcohol and antibiotics can increase your chance of developing side effects. It’s best to wait until you’re done with your antibiotic course before you have an alcoholic drink.

Soon, doctors began seeing a similar constellation of symptoms in their patients who drank alcohol.

The kidneys are in charge of getting rid of harmful substances, including medicines, from the blood and body through urine. Antibiotics can overburden and damage kidneys, which is made worse by heavy drinking. We are all aware that alcoholic drinks can be harmful to one’s health. While drinking in moderation may have no severe reaction, doing so while on antibiotics can lead to complications.
